It is a pity if you can't confirm the frame number. Possibly worth talking to Spondon, they might help with an ID. Also, the TZ350 forum and website has some frame pics to ID. Rust on the forks means very little. If they are TZ forks they are probably worth at least £1000, wheels at least £500 each, TZ engine bottom end with TZ gbox clutch / cover and crank / iggy / carbs at least £3,000 (in used condition), rear swingarm £500. So, that is what you could be talking if they are TZ parts in used condition (we know the cylinders are modified RD but, they are possibly worth a fair bit if done well). Alloy TZ tank, £1000 if good. Then, there is the frame. Could be of good value with history - even a receipt from some time ago? Unfortunately, the market for these parts is difficult. Race bike specialists will only offer peanuts because they have the contacts to sell parts to vintage racebike customers. You might get some interest if you put the "bike" up on ebay as a TZ350/250 project with as much info as you have with a (highish £9,999?) price and "or best offer", You don't have to sell, just see what offers you get! Whatever, don't undersell the TZ parts! Spend a little time on the internet searching for genuine TZ parts to see the prices, THEY AIN'T CHEAP. Cheers

Think if you made an offer at half that Chris, Blackvisor might accept.....The engine has no numbers apart from bore and stroke so cases even if they were TZ and now same as modified RD. It’s an AC TR engine not a wet TZ so obviously no water pump etc. Sum of the residual parts easy to add up....Same goes for the frame , most likely is Spondon but real pity the Spondon index number has been replaced with TR/TD VIN. As for wheels have a look at what yamaha TZ and Astralite wheel fetch in the market place..

No doubt the real race parts on this collection are much more valuable than RD equivalents but perhaps some more conservative pricing would avoid an expectation gap and associated disappointment...

Pricing parts or bikes without and provenance (especially race-bikes) is very difficult.Like anything the market dictates. In the specialist racing market the focus tends to be on three things.Does it make my bike go faster,does it make it stop better or handle better. Racers are not fashionista's for most it is budget club racing. There are probably race-bike collectors out there, but again it is all about the provenance.Evilbay tends to be the go to market these days so list it and see. But you will have all the associated hassle of dealing with time wasters and dreamers.Or sell to one buyer who will not pay retail prices . The thing is, it's worth as much as someone wants to pay.At the end of the day it is worth nothing sat in a shed or garage.

Hi Betty, thanks, I just re read the detail, I agree it does say engine numbers removed and bore x stroke. Not at all unusual for a race engine, as we know. However, with the only evidence of the pics, it is impossible to know the details of the cases and engine internals other than it has a dry clutch and an early TZ cover so, it has a TZ gbox unless it has one of the RD/TZ dry clutch conversion shafts. Blackvisor, I guess you can see the problems with these parts. Without the detailed knowledge you are not best placed to get a fair price for parts. You have got good info for the frame, swingarm, tank, wheels, forks, carbs, brakes as all are probably TZ. The cylinders look to me to be late RD and probably ported but, you need to know your stuff to be able to tell if they are valuable as race parts. As for the rest of the engine, it needs to come apart to check exactly what it is built from and condition, unless you just decide to sell as is. Also, the spares that you describe might be a goldmine!I am happy to ID parts if you put pics up, including the engine guts. Cheers
